Mifune, known by the epithet "God of the Sword", is an infamous samurai and bodyguard who acts as a guardian to the little witch, Angela Leon. He is later blackmailed into the service of Arachnophobia by its head, Arachne Gorgon. Often stoic in nature and staunch in attitude, Mifune tends to be somewhat quiet in situations that do not directly involve him and remains mostly serious as well as being straightforward, especially toward those he would consider a threat. In addition, he often swung his sword in defense of other children, possessing a great level of compassion and care for those he consider young. In battle, he is analytical, seeing slight movements and small details and immediately noting them, whether it be out loud or within the confines of his thoughts. He's also not above calling out other individuals on negative traits. Being a strong follower of the Path of a Warrior, he is willing to give respect to his opponents no matter the age, if they are also capable of fighting with their all, as fellow followers of the Path of a Warrior. Despite his honorable and strong belief in the Path of a Warrior, Mifune himself is also not infallible. Mifune seems to previously possess little regard for ordinary human life, having a history of being a part of various criminal organizations and crime families. Early on, the reasons for his alliance with them were unknown and are implied to have led him to be placed on Shinigami's List. After becoming Angela's guardian and bodyguard, however, he abandoned his previous mindset and seems to have more regard for human life, particularly that of children. He only allows himself to be employed by an organization like Arachnophobia when they leverage their ability to protect Angela.
